The Heretic demo showcases realistic digital humans in Unity

Unity Technologies has released a teaser for The Heretic, a new short film designed to showcase the game engine’s real-time rendering capabilities, as part of its keynote at GDC 2019.

The demo, which runs at 30fps in 1440p resolution on a “high-end gaming PC”, is lit entirely using real-time lights, and showcases Unity’s recent work on photorealistic digital humans.

A ‘first attempt’ at photorealistic human characters in Unity
The Heretic teaser is pretty enigmatic, with its human protagonist navigating an underground tunnel to open what may be a portal into a parallel universe.

“This makes no sense to me,” he comments to his sidekick: a shapeshifting mechanical creature that is part bird, part alien symbiote and part robotic spider.

However, like Unity’s previous tech demos Adam and Book of the Dead, the point of The Heretic isn’t really the storyline, but to showcase Unity’s developing photorealistic rendering capabilities.

Unity describes the work as a “first attempt” at photorealistic human characters “scoped very conservatively with the primary purpose to establish a pipeline and a bar of quality”.

The lead character is based on real-world scan data captured by UK service bureau Infinite-Realities, processed using Russian3DScanner‘s facial topologisation technology.
